EXTENSION-BED.

SPECIFICATION forming part of Letters Patent No. 611,115, dated September 20, 1898.

Application led October 13, 1897@ Serial No. 655,058. (Ncmodel.) v

To all whom, t may concern.-

Be it known that we, ALFRED W. FURNI- vALL and HENRY MARTIN, of New York, (Astoria, Long Island Oity,) in the county of Queens and State of New York, have invented l character and adjustable in length.

The invention also consists of certain improved constructions, which will be hereinafter described, and particularly pointed out in the claims.

Figure l shows our improved bed in perspective. Fig. 2 is a fragmentary perspective showing the method ofattaching the parts to the posts, said parts being slightly detached to more fully show their shape. Fig. 3 is a plan view showing one of the side rails and the attachment of the same to the posts and to the springs. Fig. 4is a cross-sectional elevation taken upon the line 4 4 of Fig., 3, showin g the construction of the side rails; and Fig. 5 is a perspective showing the construction of the springs.

The object of our invention is to construct a bed which may be adjusted both in width and length to suitthe requirements of different circumstances. With this obj ect in View the side and end rails are each made in two parts, said parts being telescopic or otherwise adjustable upon each other, so that the rails may be lengthened or shortened, as desired. The side rails A are adjustable independently of the end rails B. These rails are formed inl two pieces Al Aand A2, which may be of any suitable shape which is capable of adjustment one upon the other, so as to vary the length of the rail. The form of preferred construction is shown in the drawings.` This consists,as'

shownA most clearly in Fig. 4, of a rail formed of -two plates which are bent so as to form vertical and horizontal flanges G and G,which are united by a bulb G2. This bulb, as shown in Fig. 4, is of circular outline and is of difof the bulb is made such that the inner bulb cannot be pulled laterally out of the outer but .can move relatively thereto only by sliding longitudinally. The vertical flanges G are preferably made both of lthe same width, so that their upper lines willcoincide. The horizontal flanges, however, vary in width. The plate which is outermost has the broader horizontal flange. This is necessitated by reason of the fact that the rails are provided with pins a upon the inner edge of the horizontal flanges, said pins being used as an attachment for the springs. The inner rail having the narrower flange may slide within the line of the pins a upon the outer flange, thus preventing interference with the same. The end rails Bare similarly formed, eX- cepting that they are not provided with pins a for attachment of the springs. The two pieces of the rail may be secured at any point by means of la screw g, which passes through thehorizontal lian-ge G of the outer rail and bears against the corresponding ange of the innerrail. As this screw is set up it bends the inner rail in the bulb G2, so as to bind it in the outer rail vand prevent sliding. They might also be secured by means of a pin dropped into registrable holes in both. The ends of the rails are secured to blocks F at each c orner by means of screwsa or any other suitable device. The use of screws is preferred,'as the bed may be readily taken apart. These blocks are provided with verlow the same. The pin ff, extending below .the block, is threaded and adapted to screw into the threaded socket C' in the leg orsupport C. The upwardly-extending pin f is adapted to fit within the hollow lower end d of the post D. This post D may be solid and have a socket formed in its lower end or be made of a tube 0f Isuch a size as to fit over the pin f. The posts D are provided with horizontal inwardly-extending bars d, which are preferably round. These bars slide within tubes e of the head and foot piecesl E. The construction shown in the drawings is one which lwould be used in connection with an iron IOO composed of the horizontal bars e and the vertical connecting-rods e. In this case the horizontal rods e are so placed that they register with the rods d, fixed upon the posts D, said rods sliding within the tubes e. By this means the head-piece is retained centrally on thebed at any adjustment, the adjustment being secured at each end thereof. In other constructions horizontal tubes corresponding with the tubes e would be secured to the head and foot pieces to receive the rods d and to permit of the adjustment described.

The block F, to which the rails are attached, is provided with a bead f3, corresponding in shape with the bulb or bead Gl2 of the rails, thus presenting a uniformity of appearance. The springs designed for this bed are shown in perspective in Fig. 5. These consist ot short sections which extend across the bed and which are formed of two spring-plates which are reversely curved or bent into an S shape. rlhese plates thus consist of the top horizontal portion H', the bottom horizontal portion H3, and the central connecting portion H2, the outer edges of the horizontal portions having a curved edge H4, which interlocks with the edge of the other plate, so as to secure the two together and prevent lateral displacement. These plates are so bent that one plate will slide longitudinally upon the other, but cannot be displaced laterally. The outer ends of the plates are provided with holes h, adapted to fit over the pins a upon the side rails. The plates forming the springs are thus enabled to slide upon each other, so as to vary the length of the spring and accommodate themselves to the varyingr width of the bed. In changing the length of the bed one or more of the spring-sections would be removed or replaced, as necessary. i

bed and may be varied equally in length. It may also be readily taken apart for storage or transportation.

The form of springs shown in connection with the bed will not sag in the center, and they are of such construction that they arel durable and cheap in first cost.
